Peter is right, the days of simple imports to NZ ended just recently. What you have to do is prove your vehicle complies with the standards set in one or more of the countries that the NZ authorities recognise as having compatible or better standards than in NZ. This is better than some countries (for example Australia or the USA) where it's almost impossible to register a vehicle that was not originally imported into that country.
I'm assuming it's a South African new vehicle? The website Peter gave should have a list of countries that qualify.
What brand is it?
